Error response for Indication sent by nRF8001

Question

I'm using an nRF8001 with a local GATT service and characteristic with Indications.
This corresponds to figure 29 in the Product Specification. 
 When the peer sends a Confirmation, I get a DataAckEvent as expected. 
 When the peer sends an Error Response, I receive no event from the nRF8001. Instead, the connection is terminated automatically by the nRF8001 after 30 seconds. 
 Is there a way to receive this Error Response? I would expect a PipeErrorEvent to be generated by the nRF8001.

Hi Stephan, 
 As per Bluetooth specification no error response shall be sent in response to a Indication or Notification. 
 www.bluetooth.org/.../adopted-specifications Core Version 4.0 Volume 3 Part F 3.4.9. 
 If you receive an error response to a indication, then this is a spec violation as indications shall be confirmed if they have been received by the host.
